It is a linguistic commonplace to say that the meaning of text is more than the conjunction of the meaning of its sentences. But what exactly are the rules that govern its interpretation, and what are the constraints that define well-formed discourse? For a long time, the development of precise frameworks of discourse interpretation has been hampered by the lack of a deeper understanding of the dependencies between different discourse units. Recent years have seen a considerable advance in this field. A number of strong constraints have been proposed that restrict the sequencing and attaching of segments at various descriptive levels, as well as the interpretation of their interrelations. The availability of annotated corpora has also helped to confront key hypotheses with observable phenomena.

The goal of this workshop is to provide a forum for presenting recent research on constraints in discourse. The target areas include the recognition of discourse structure as well as the interpretation and generation of discourse in a broad variety of domains. The workshop offers a forum for researchers from diverse formal approaches, including but not limited to:

• Rhetorical Structure Theory (RST)
• Segmented Discourse Representation Theory (SDRT)
• Discourse Tree Adjoining Grammars
• Head-driven Phrase Structure Grammar (HPSG)
• The QUD Modell
• Plan Based Reasoning
• Abductive Reasoning
• Gricean Pragmatics
• Speech Act Theory

The conference invite talks that further our theoretical understanding of the role of constraints in discourse, as well as empirical studies that shed light on theoretical issues about discourse structure or interpretation.. The conference is explicitly intended for discussion and comparison of theoretical accounts that lay the ground for applications. It is not intended as a platform for system demonstrations. Specific topics might relate to

• Anaphora Resolution
• Co-reference
• Dialogical vs. Monological Discourse
• Questions and Answers
• Lexicon and Discourse Relations
• Cognitive Modeling
• Underspecification and Nonmonotonic Inferences
